Flammability of alkanes
WebAug 5, 2024 · Alkenes are more reactive than alkanes (and the flames are hotter) and alkynes more reactive still. So the hottest widely used flame in welding in the oxy-acetylene flame. Many casual explanations online seem to get the nature of this effect wrong, claiming that the acetylene triple bond "has a lot of energy to release" which is just wrong. WebJul 14, 2024 · The compound at the far right, discovered after the other two, was named neopentane (from the Greek neos, meaning “new”). Although all three have the same molecular formula, they have different properties, including boiling points: pentane, 36.1°C; isopentane, 27.7°C; and neopentane, 9.5°C.

WebAlkanes are saturated hydrocarbons (substances composed solely of carbon and hydrogen, with only single bonds); alkanes have a general formula C H 2 + 2. Alkynes are hydrocarbons whose molecules contain a carbon–carbon triple bond; they have the general formula C H 2 – 2. WebAlkynes always contain a triple bond. Alcohols contain at least one oxygen atom. Amines contain at least one phosphorus atom. Carboxylic acids contain at least two oxygen atoms. An aldehyde contains a double bond. Amines contain at least one phosphorus atom. Which of these does not always have a double bond? amine aldehyde ketone alkene
